Question

Find the equation of the quadratic function with zeros at -1, and 1 and vertex at (0, -6)

Answer 1

tmi

Answer 2

the zeros tells you it looks like
\[y=a(x-1)(x+1)\] and you know \((0,-6)\) is on the graph
repalce \(x\) by 0 and set the result equal to \(-6\) and solve for \(a\)

Answer 3

in other words, solve \(-6=a(-1)\times 1\)

Answer 4

y=a(x−1)(x+1)
